Open rtfmjoey opened 4 months ago

rtfmjoey commented 4 months ago

Describe the bug Followed the documentation to install mqtt-io and configured module:

gpio_modules:
  - name: c2
    module: gpiod
    chip: /dev/gpiochip1

Starting mqtt-io results in the following error:

I believe mqtt-io depends on an old version of gpiod. Running pip install "gpiod<2.0.0" solved this issue for me
